'68 Yenko, Transplant vs. COPO

KurtS;
Are you saying that the V78 could be for a different trim tag size or design??

Here is a pic of a what I believe is a Corvette L72 fuel pump. (Rowdyrat, confirm????)If it is, I can see why they would have to change it in order to put the L72 into the Camaro subframe. Could this be why they wrote the notes on the test paperwork?

If the car used the L88's Holley 850 double pumper carb Chevy Engineering would probably specify the L88 fuel pump. The L88 fuel pump was probably in short supply since not many L88s were built and would have to come from the Corvette plant so maybe there was a problem getting the L88 fuel pump or maybe the Corvette L88 pump would not fit in the Camaro. It appears they just put in a fuel pump to make the car driveable then let Yenko worry about replacing it. A 1968 Camaro with a L72 427 equipped with L88 parts, an M22, and 4:56 gear would be a quick drag car. It's too bad Chevy didn't make the 50 cars required to qualify it for NHRA like they did with the ZL1.

When did GM start using the double pumper? Was it in '69 only? Weren't there availablity problems when the ZL-1s came out? Wasn't it Charley's ZL-1 that started out with a vacuum secondary because Holley hadn't delivered the 850s yet?

When did Holley start making the double pumper?

I believe the 1967-68-69 L88 Corvette and ZL1 Camaro used the 850 Holley DP. When the Gibb/Harrell ZL1 went to its first race it failed tech inspection for not having the correct factory numbers on the Holley. It was discovered to have a 780 Holley on it instead of the correct 850 Holley. When Cars magazine tested Charlie's #3 ZL1 it had the incorrect 780 and still ran 13.16 @ 110.21. I'm surprised no L88s or ZL1s have shown up at the Pure Stock Drags. They sould be among the quickest factory built cars ever made.

Hassett had his ZL-1 at the FSCMDR in Ohio last year. I'm not sure if he's gonna have it back this year or not, or if he's bringing another car.

You out there, Mark?

My understanding of V78 mandatory is that export vehicles, especially the Camaros that were ordered for Canada, did not have to comply with air pumps or even having the L72 engines installed if the vehicles were ordered under COPO paperwork.
